37 <P><STRONG>Description</STRONG>
38 <P>The <B>vos backup</B> command clones the indicated read/write volume to
39 create a backup version, placing it at the same site as the read/write
40 version. The backup volume's name is the same as the read/write
41 source's with the addition of the <B>.backup</B>
42 extension. Its volume ID number is the one allocated for it in the
43 Volume Location Database (VLDB) when the read/write source was created with
44 the <B>vos create</B> command. If a backup version already exists,
45 the new clone replaces it.
46 <P>To create a backup version of multiple volumes, use the <B>vos
47 backupsys</B> command.
48 <P><STRONG>Options</STRONG>
51 </B><DD>Specifies either the complete name or volume ID number of the read/write
54 </B><DD>Names the cell in which to run the command. Do not combine this
55 argument with the <B>-localauth</B> flag. For more details, see the
56 introductory <B>vos</B> reference page.
58 </B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
59 issuer. Do not combine this flag with the <B>-localauth</B>
60 flag. For more details, see the introductory <B>vos</B> reference
63 </B><DD>Constructs a server ticket using a key from the local
64 <B>/usr/afs/etc/KeyFile</B> file. The <B>vos</B> command
65 interpreter presents it to the Volume Server and Volume Location Server during
66 mutual authentication. Do not combine this flag with the
67 <B>-cell</B> argument or <B>-noauth</B> flag. For more details,
68 see the introductory <B>vos</B> reference page.
70 </B><DD>Produces on the standard output stream a detailed trace of the
71 command's execution. If this argument is omitted, only warnings
72 and error messages appear.
74 </B><DD>Prints the online help for this command. All other valid options
77 <P><STRONG>Output</STRONG>
78 <P>The following message confirms that the command succeeded:
79 <PRE> Created backup volume for <VAR>volume name</VAR>
82 <P><STRONG>Examples</STRONG>
83 <P>The following example creates a backup version of the volume
85 <PRE> % <B>vos backup user.smith</B>
86 Created backup volume for user.smith
89 <P><STRONG>Privilege Required</STRONG>
90 <P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
91 the machine specified with the <B>-server</B> argument and on each
92 database server machine. If the <B>-localauth</B> flag is included,
93 the issuer must instead be logged on to a server machine as the local
94 superuser <B>root</B>.
